## Background
FIELD
Embodiments described herein relate to electronic gaming machines. The embodiments described herein particularly relate to an enhanced electronic gaming machine with a rotatable three-dimensional game surface.
INTRODUCTION
Various video gaming terminals or machines may consist of slot machines, online gaming systems (that enable users to play games using computer devices, whether desktop computers, laptops, tablet computers or smart phones), computer programs for use on a computer device (including desktop computer, laptops, tablet computers of smart phones), or gaming consoles that are connectable to a display such as a television or computer screen.
Video gaming machines may be configured to enable users to play a variety of different types of games. Example games may involve a matrix or grid of cells, where gaming symbols or elements may be displayed within the cells. One type of game displays a plurality of moving arrangements of gaming elements (such as reels, and symbols on reels) within a matrix. Another type of game displays gaming elements within a matrix in a fixed arrangement such as a Keno or Bingo type game. Players may wager on gaming outcomes. One or more winning combinations may be displayed using a pattern of gaming elements in an arrangement of cells (or an “array”) of the matrix, where each cell may include a gaming element, and where gaming elements may define winning combinations (or a “winning pattern”). Games that are based on winning patterns may be referred to as “pattern games”.
One example of a pattern game is a game that includes spinning reels, where a user wagers on one or more lines, activates the game, and the spinning reels are stopped to show one or more patterns in an array. The game rules may define one or more winning patterns of gaming elements, and these winning patterns may be associated with credits, points or the equivalent.
Another example type of game may be a Keno or Bingo type game where different gaming elements are activated that correspond to one or more gaming elements in the cells of the matrix, and the activated gaming elements may be used to define one or more winning combinations.
Gaming systems or machines of this type are popular. However, there is a need to compete for the attention of users, and therefore it is necessary to innovate by launching games with new and engaging game features.

DETAILED DESCRIPTION
Embodiments described herein relate to an electronic gaming machine (EGM) that includes a three-dimensional (3D) graphics processor, and provides games with 3D enhanced game components, e.g., game symbols, game surfaces, and the like.
In particular, the EGM is configured to generate a 3D game surface for a given game in accordance with a set of game rules, and to present a view of the 3D game surface such that a plurality of game symbols displayed on the surface are viewable. The EGM is configured to rotate the view of the 3D game surface in response to a game event such that one or more additional game symbols become viewable, and the additional game symbols are then integrated into the given game in accordance with the game rules.
The given game may be any of a variety of game types, such as a reel-type game, a keno-type game, a bingo-type game, and so on, and the game symbols may relate to any of these game types.
The EGM may be embodied in a variety of forms and devices including, for example, portable devices, such as tablets and smart phones, that can access a gaming site or a portal (which may access a plurality of gaming sites) via the Internet or other communication path (e.g., a LAN or WAN). The EGM may be located in various venues, such as, e.g., a casino or an arcade. One example type of EGM is described with respect to FIG. 1.
FIG. 1 is a perspective view of an EGM 10 adapted to provide games with 3D enhanced game components, exemplary of an embodiment. EGM 10 includes a display 12 that may be a thin film transistor (TFT) display, a liquid crystal display (LCD), a cathode ray tube (CRT), auto stereoscopic three-dimensional display and LED display, an OLED display, or any other type of display. An optional second display 14 provides game data or other information in addition to display 12. Display 14 may provide static information, such as an advertisement for the game, the rules of the game, pay tables, pay lines, or other information, or may even display the main game or a bonus game along with display 12. Alternatively, the area for display 14 may be a display glass for conveying information about the game. Display 12 or 14 may also include a camera, sensor, and other hardware input devices.
Display 12 or 14 may have a touch screen lamination that includes a transparent grid of conductors. Touching the screen may change the capacitance between the conductors, and thereby the X-Y location of the touch may be determined. A processor of EGM 10 associates this X-Y location with a function to be performed. Such touch screens may be used for slot machines, for example. There may be an upper and lower multi-touch screen in accordance with some embodiments.
One or both of display 12 and 14 may be configured to have auto stereoscopic three-dimensional functionality.
A coin slot 22 may accept coins or tokens in one or more denominations to generate credits within EGM 10 for playing games. An input slot 24 for an optical reader and printer receives machine readable printed tickets and outputs printed tickets for use in cashless gaming.
A coin tray 32 may receive coins or tokens from a hopper upon a win or upon the player cashing out. However, EGM 10 may be a gaming terminal that does not pay in cash but only issues a printed ticket for cashing in elsewhere. Alternatively, a stored value card may be loaded with credits based on a win, or may enable the assignment of credits to an account associated with a computer system, which may be a computer network connected computer.
A card reader slot 34 may accept various types of cards, such as smart cards, magnetic strip cards, or other types of cards conveying machine readable information. Card reader slot 34 is coupled to a card reader (e.g., card reader 49 of FIG. 2).
Alternatively, an electronic device may couple (by way of a wired or wireless connection) to EGM 10 to exchange electronic data signals to transfer player credits and the like. For example, near field communication (NFC) may be used to couple to EGM 10, which may be configured with NFC-enabled hardware. This is a non-limiting example of a communication technique.
A keypad 36 may accept player input, such as a personal identification number (PIN) or any other player information. A display 38 above keypad 36 displays a menu for instructions and other information and provides visual feedback of the keys pressed.
Keypad 36 may be a input device such as a touchscreen, or dynamic digital button panel, in accordance with some embodiments.
Player control buttons 39 may include any buttons or other controllers needed to play the particular game or games offered by EGM 10 including, for example, a bet button, a repeat bet button, a spin reels (or play) button, a maximum bet button, a cash-out button, a display pay lines button, a display payout tables button, select icon buttons, and any other suitable button. Buttons 39 may be replaced by a touch screen with virtual buttons.
EGM 10 may also include a digital button panel. The digital button panel may include various elements such as for example, a touch display, animated buttons, frame light, and so on. The digital button panel may have different states, such as for example, standard play containing bet steps, bonus with feature layouts, point of sale, and so on. The digital button panel may include a slider bar for adjusting the three-dimensional panel. The digital button panel may include buttons for adjusting sounds and effects. The digital button panel may include buttons for betting and selecting bonus games. The digital button panel may include a game status display. The digital button panel may include animation. The buttons of the digital button panel may include a number of different states, such as pressable but not activated, pressed and active, inactive (not pressable), certain response or information animation, and so on.
EGM 10 may also include hardware configured to provide motion or gesture tracking. An example type of motion tracking is optical motion tracking. The motion tracking may include a body and head controller. The motion tracking may also include an eye controller. EGM 10 may implement eye-tracking recognition technology using a camera, sensors (e.g. optical sensor), data receivers, and other electronic hardware. The camera may be used for gesture or motion tracking of player, such as detecting player positions and movements, and generating signals defining x, y and z coordinates. A gesture or motion by a player may trigger a game event that causes a 3D game surface displayed at EGM 10 to rotate, as detailed below.
EGM 10 may also include a plurality of effects lights and frame lights. The lights may be synchronized with enhancements of the game. EGM 10 may be configured to control color and brightness of lights. Additional custom animations (color cycle, blinking, etc.) may also be configured by EGM 10. The custom animations may be triggered by certain game events.
EGM 10 may also include an output device such as one or more speakers. The speakers may be located in various locations on EGM 10 such as in a lower portion or upper portion. EGM 10 may have a chair or seat portion and the speakers may be included in the seat portion to create a surround sound effect for the player. The seat portion may allow for easy upper body and head movement during play. Functions may be controllable via an on-screen game menu.
EGM 10 may be configurable to provide automated control over some or all of the functionality detailed above (effects lights, frame lights, sounds, and so on).

In an embodiment, gaming server 80 may include hardware components substantially similar to those shown in FIG. 3B.
In an embodiment, gaming device 60 and/or gaming server 80 may be implemented using multiple devices, multiple databases, or multiple storage devices distributed over a wide geographic area and connected via a network (which may be referred to as “cloud computing”).
In an embodiment, EGM 10 and gaming server 80 may be integrated as a single system or a single device.
EGM 10 may be configured to provide 3D enhancements to one or more games playable at EGM 10. The enhancements may be enhancements to a primary game, or may be enhancements to a secondary or bonus game.
In an embodiment, the 3D enhancements relate to generating and presenting a rotatable 3D game surface for displaying game symbols in accordance with a given game. Additional game symbols are revealed as the game surface is rotated, and such additional game symbols are integrated into the given game.
FIG. 4 is a flowchart that depicts exemplary blocks 400 and onward performed at EGM 10 to provide 3D enhancements relating to the rotatable 3D game surface. As will be appreciated, although exemplary operation is described with reference to EGM 10, substantially similar blocks may be performed in a distributed manner at gaming device 60 and gaming server 80.
Before blocks 400 and onward are performed at EGM 10, an electronic datastore at EGM 10 is populated with game data for one or more games. The games may include any of the various game types noted above. The game data includes a set of game rules for each of the games.
A particular game is selected by the player for play at EGM 10. The particular game may also be selected by EGM 10 without user input. The game may be a primary game, a secondary game, or a bonus game.
EGM 10 performs blocks 400 and onward by executing instructions at one or more processors, e.g., at processor 56 in cooperation with 3D graphics processor 54. The instructions may be stored in memory 58.
When a game begins, at block 402, EGM 10 generates a 3D game surface for displaying game symbols. The 3D game surface may be generated using at least 3D graphics processor 54.
The 3D game surface may be generated in accordance with the rules for the current game. For example, when the current game is a spinning reel game, the 3D game surface may be generated to include a plurality of reels, each having one or more game symbols for the reel game. EGM 10 determines the rules for the current game using game data stored at its electronic datastore.
At block 404, EGM presents a view of the generated 3D game surface on an electronic display, e.g., display 12 or display 14, such that a plurality of game symbols are viewable. The view may, for example, be an isometric view, a perspective view, a side view, or the like. The view may be rendered, for example, by 3D graphics processor 54.
FIG. 5 shows an exemplary view 100 of a 3D game surface 110, exemplary of an embodiment. Surface 110 has a cylindrical shape, and displays a plurality of game symbols 102 thereon. Symbols 102 are arranged in a grid, with each column of the grid corresponding to a reel having three symbols.
Surface 110 includes an active game region 112 containing those game symbols 102 that are activatable within a current game. For example, activatable game symbols 102 may include symbols that are capable of interacting with each other during the current game, e.g., to form winning combinations. Activatable game symbols 102 may include symbols that are capable of user selection during the game.
Surface 110 may also include game symbols 102 that are viewable, but are not activatable within the current game. Such game symbols 102 may include symbols that were previously activatable within the current game. Such game symbols 102 may also include symbols that may become activatable within the current game, e.g., when the symbols are integrated into the current game in manners detailed below. In view 100, surface 110 displays a plurality of such non-activatable game symbols 102 in column (reel) 104 and in column (reel) 106.
Each game symbol 102 may have a particular image, number, shape, color, theme, etc. Game symbols 102 may be associated with different payouts, in accordance with game rules. Game symbols 102 may interact with like symbols, e.g., symbols having similar images, numbers shapes, colours, themes, etc., to form winning combinations in accordance with game rules. Game symbols 102 may include special symbols, e.g., wildcard symbols that interact with any other symbol and therefore provide a higher likelihood of forming winning combinations.
EGM 10 may populate game surface 110 with game symbols 102 selected according to the rules of the current game. EGM 10 may populate game surface 110 with game symbols 102 that are selected randomly.
Game symbols 102 displayed on 3D game surface 110 may change as the game is played. For example, one or more reels displayed on surface 110 may be spun to change the displayed game symbols 102. Game symbols 102 may also change in response to user input.
EGM 10 may rotate the view of 3D game surface 110, e.g., in response to pre-defined game events.
Such game events may include, for example, the beginning or ending of a round of the current game. In such case, rotation of game surface 110 may represent a reward for a player's progress through the current game.
Such game events may include, for example, the beginning or ending of a bonus game or a secondary game associated with the current game. In such case, rotation of game surface 110 may represent a reward for triggering or completing the bonus game or the secondary game.
Such game events may include, for example, activation of a particular game symbol 102. For example, one or more game symbols 102 may be defined as being a “rotate” symbol, and game surface 110 may rotate when a “rotate” symbol becomes activated, e.g., when it becomes selected by the player or when it forms part of a winning combination. Rotate symbols may be visually distinguished from other symbols.
Such game events may also include, for example, expiry of a pre-defined time period. In such case, rotation of the game surface 110 may be scheduled for particular time intervals, e.g., every minute, or every few minutes.
Such game events may also include, for example, receipt of a user request to rotate surface 110. The user request may be issued, for example, through an input 50 (FIG. 2A). In an embodiment, EGM 10 may include a button indicated to be a “rotate” button, and the user request may be issued by pressing or otherwise activating that button. In an embodiment, EGM 10 may include multiple buttons, each associated with a request to rotate surface 110 in a particular desired direction. In an embodiment, EGM 10 may include a touchscreen (e.g., a touchscreen integral to display 12 or display 14), the user request may be issued by a user swiping the touchscreen. The direction of the user's swipe may indicate a desired direction in which to rotate surface 110.
Referring once more to FIG. 4, at block 406, EGM 10 rotates the view of 3D game surface 110 in response one of the above-noted game events.
EGM 10 may rotate the view of 3D game surface 110 by rotating surface 110, e.g., to change an angular position of surface 110 relative to a position of a virtual camera used to render the view. EGM 10 may also rotate the view of 3D game surface 110 by rotating the virtual camera about surface 110. EGM 10 may also rotate the view by rotating both surface 110 and the virtual camera.
Rotating the view of 3D game surface 110 causes additional game symbols 102 to become at least partially visible on surface 110, e.g., as such symbols are rotated towards a viewable front portion of surface 110. Rotating the view of 3D game surface 110 may also cause some previously visible game symbols 102 on surface 110 to at least partially be removed from view, e.g., as such symbols are rotated towards an unviewable back portion of surface 110.
FIG. 6 shows a view 100 of 3D game surface 110, rotated relative to the view 100 of FIG. 5. In particular, view 100 has been rotated in a clockwise direction 150, i.e., towards the left. In the rotated view 100, additional game symbols become viewable, i.e., game symbols 102 in column (reel) 108. Further, in the rotated view 100, some game symbols 102 have disappeared from view, i.e., game symbols in former column (reel) 104 (FIG. 5).
In an embodiment, the direction of rotation (e.g., clockwise or counter-clockwise) may be pre-defined. In an embodiment, the direction of rotation may be selected by EGM 10. In one example, the direction of rotation may selected based on the particular game type. In another example, the direction of rotation may be selected based on the particular game event triggering the rotation. For example, when the game event is a user request, the direction may be user specified. Similarly, when the game event includes activation of a particular game symbol (e.g., a rotate symbol), the direction may be determined by the particular game symbol.
In an embodiment, the magnitude of rotation may be pre-defined. The magnitude may, for example, be defined to bring into view a desired quantity of additional game symbols. The desired quantity of game symbols may, for example, be one column, or several columns. So, for example, in a spinning reel game, EGM 10 may be configured to bring an additional reel, or a particular number of additional reels, into view each time that game surface 110 is rotated. Conversely, the magnitude may, for example, be defined to remove from view a desired quantity of game symbols 102. In an embodiment, the magnitude of rotation may be selected by EGM 10. In one example, the magnitude of rotation may be selected to be proportional to a player's winnings. So, for example, the player may be rewarded for successful play with a particular large rotation that brings into view a large quantity of additional game symbols. In another example, the magnitude of rotation may be selected to be proportional to how long the current game has lasted. So, for example, the player may be rewarded for long play.
When the view of 3D game surface 110 rotates, additional game symbols 102 may be integrated into the current game to become activatable symbols. For example, FIG. 6 depicts a column (reel) 106 containing game symbols 102 that have been rotated into active game region 112. These additional game symbols 102 in column 106 may be integrated into the current game in accordance with the games rules. In one example, game symbols 102 integrated into the current game may become user selectable. In another example, game symbols 102 integrated into the current game may become capable of interacting with other game symbols 102 in the current game.
In an embodiment, when 3D game surface 110 rotates, the additional game symbols 102 that are integrated into the current game are symbols that have been brought into view by the rotation. In an embodiment, the additional game symbols 102 that are integrated into the current game are not symbols that have been brought into view by the most recent rotation, but rather may be symbols brought into view by a prior rotation.
In an embodiment, EGM 10 may generate 3D game surface 110 such that expected winnings of the current game change as the view of 3D game surface 110 is rotated. For example, surface 110 may be generated such that expected winnings increase each time the view is rotated in a pre-defined direction (e.g., in a clockwise direction). Surface 110 may also be generated such that expected winnings decrease each time the view is rotated in the opposite direction (e.g., in a counter-clockwise direction).
In one example, EGM 10 is configured to provide additional game symbols 102 that are associated with higher payouts as the view of surface 110 is rotated in a pre-defined direction. In another example, EGM 10 is configured to provide additional wildcard symbols (e.g., symbols 114) as the view of surface 110 is rotated a pre-defined direction, as shown, for example, in FIG. 7.
In an embodiment in which game symbols 102 are selected randomly for display on surface 110, EGM 10 may be configured to generate additional wildcard symbols or additional symbols associated with higher payouts at a higher frequency as the view is rotated. In this way, EGM 10 may reward a player for game progression, e.g., successful play or long play, thereby creating an incentive for game progression.
In an embodiment, EGM 10 may be configured to provide a preview of one or more additional game symbols 102 that are available for integrating into the current game. For example, EGM 10 may provide the preview by rotating the view of the 3D game surface in a pre-defined direction such that one or more additional game symbols 102 become viewable, and then rotating the view in the opposite direction such that the additional game symbols are no longer viewable. So, EGM 10 may temporarily change the view to preview symbols 102, and may then restore the initial view. Game symbols previewed in this manner are not integrated into the current game. Players, upon receiving a preview of game symbols 102, may be encouraged to continue playing to cause the previewed symbols 102 to be integrated into the current game.
In the depicted embodiment, EGM 10 generates a 3D game surface 110 having a cylindrical shape for displaying a particular arrangement of game symbols. In another embodiment, EGM 10 may generate a 3D game surface having a cylindrical shape with a different diameter and/or a different height. Such 3D game surfaces may be adapted to display a different arrangement of game symbols. For example, game symbols may be arranged in a grid such that each column of symbols includes a greater or fewer number of game symbols. Further, a fewer or greater number of columns may be visible on the surface of the 3D game surface. For example, FIG. 8A depicts a 3D game surface 200, exemplary of an embodiment. 3D game surface 200 displays fewer columns of symbols than 3D game surface 110, but includes a greater number of game symbols in each column. In another embodiment, EGM 10 may generate a 3D game surface that is not cylindrical in shape. For example, the 3D game surface may, for example, have a spherical shape, a torus shape, a conic shape, a prism shape (e.g., octagonal or decagonal prism), or the like. For example, FIG. 8B depicts a 3D game surface 200 having a spherical shape, exemplary of an embodiment.
In an embodiment, the game provided at EGM 10 may be a wagering game. In this embodiment, EGM 10 may be configured to receive wagers from the user.
